LPCScrypt not working with dfu-util 0.10 on Linux

jdj — Fri, 16 Apr 2021 10:14:13 GMT

Since there isn't a dedicated subforum for LPCScrypt, I'm posting here.

The script dfu_boot included in the package fails with dfu-util 0.10.

There is a bug in checking dfu-util version. What, presumably, was a check for version 0.1, checks only the first three characters. Depending on this check, different VID:PID formatting is (in this case incorrectly) used. This makes the script fail at find the correct device in the output of dfu-util -l.

Most likely this check can be dealt away with in it's entirety, since version 0.5 is dated at 2012. As seen here 0.1 did indeed use different formatting.

Below is a quick patch (which works for me) removing that test and the used variable entirely.

My version of dfu-util is 0.10, the current Manjaro community package.

Hj jdj,

To check your issue, please answer me below questions:

1. Which version of LPCScrypt do you work with? Please make sure you use the latest LPCScrypt v2.1.2 which can be downloaded from this url

https://www.nxp.com/design/microcontrollers-developer-resources/lpc-microcontroller-utilities/lpcscrypt-v2-1-2:LPCSCRYPT?tab=Design_Tools_Tab

2. Do you use NXP demo board? if yes, which one? If your own PCB, which part do you use?

3. steps of how to reproduce your issue?

Thanks,

Jun Zhang

Latest LPCScrypt.
LPC-Link2 - I was trying to program it with debugger firmware
While it is not officially supported, easiest way would be using Arch or Manjaro Linux with the community/dfu-util package - after fixing the script (by removing that version check) it works. But any Linux with dfu-util version 0.10 would work. As of now I'm not aware of any point release distribution using it.

I encountered this same problem with LPCScrypt 2.1.2 and dfu-util 0.11. LPCScrypt on Windows, since it includes its own dfu-util, is fine, but on Linux I had trouble flashing the Link2 probe on my LPCXpresso51U68. I just commented out the line in dfu_boot that sets vp_hex to '0x'. Equivalent sed command:
sudo sed -i 's/\[ \"\${dfu_ver/#[ "\${dfu_ver/' /usr/local/lpcscrypt/scripts/dfu_boot

I think rather than querying the version and deciding how to parse vid/pid, it would be better to query the vid/pid itself.
